Metric Conversions for TEAS 7

Correct Answer: A

Rationale: To convert 0.07 to a fraction, we need to write it as 7/100 since 0.07 is equivalent to 7/100 in fraction form. The correct answer is A (7/100). Choice B (7/50) is incorrect because 0.07 is not equivalent to 7/50. Choice C (7/25) is incorrect as well since it does not represent 0.07. Choice D (7/10) is incorrect because 0.07 is not equal to 7/10. The closest fraction to 0.07 is 7/100, making it the correct answer.

Correct Answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply by 1000 because there are 1000 milliliters in 1 liter. So, 0.5 liter x 1000 = 500 ml. Choice B, 50 ml, is 10 times less than the correct answer. Choice C, 5 ml, is 100 times less than the correct answer. Choice D, 0.5 ml, is 1000 times less than the correct answer.

Correct Answer: B

Rationale: The correct answer is B: France. The metric system was developed in France during the French Revolution in the late 18th century. The French Academy of Sciences proposed the system to standardize measurements for scientific and commercial purposes. France played a significant role in promoting and spreading the use of the metric system worldwide. Germany (A), Italy (C), and Spain (D) did not have a direct role in the development of the metric system.

Correct Answer: A

Rationale: To convert 0.20 liters to milliliters, we know that 1 liter is equal to 1000 milliliters. Therefore, 0.20 liters = 0.20 x 1000 = 200 milliliters. So, the correct answer is A: 200 ml. Choice B (20 ml) is incorrect as it represents 0.02 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it is the result of incorrectly multiplying 0.20 liters by 1000 twice.

Correct Answer: A

Rationale: Certainly! To express 10^6 m in simpler terms, we need to convert meters to kilometers. 1 kilometer is equal to 1000 meters. Therefore, 10^6 m = 1,000,000 m = 1 km. Option A is correct because 1 kilometer is the equivalent of 10^6 meters. Options B, C, and D are incorrect because they represent larger units of measurement than meters. Megameter is 1,000,000 meters, gigameter is 1,000,000,000 meters, and terameter is 1,000,000,000,000 meters, making them larger than 10^6 meters.
